What if your bike has a thermostat? Do you let the bike run until it opens up so the other radiator can fill?

[@robertbotta6536]

Really well done. Thank you.

Do new rads require a flush through before installation and first use?

Flush the system with water and replace with whatever coolant you want

[@chriswebb383]

Don’t let it idle like that . It’s getting hot and boiling over .

Is it a bad idea to install larger more capable radiators than the stock ones?

[@jaimeheredia6738]

No if anything larger radiators will improve the cooling system
